To all whom it may concern.-

Be it known that I, LARs ANDERSON, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illi- 1101s,have invented certain new and useful following is a full, clear, andexact specificaefficient means for keeping the spray substan- -tiallycentral with relation tothe current of air notwithstanding any increaseor diminution in the volume of the air resultingi'rom the manipulationof the air-controlling valve, thus insuring at all times a uniform orthorough mixture of the air and fuel whether the latter be in a liquidor a gaseous form.

A. further object of the invention is to provide improved means wherebythe level of the liquid fuel in the float-chamber may be varied at thewill of the operator to suit the requirements of the carbureter.

With a view to the attainment of these ends and the accomplishment ofcertain other objects, which Wlll hereinafter appear, the inventionconsists in certain features of novelty in the combination,construction, and arrangement of parts hereinafter described withreference to the accompanying 'drawin s and more particularly pointedout inthe c aims.

In the said drawings, Figure 1 is a side elevation of in improvedcarbureter looking into the disc arge side thereof. Fig. 2 is anelevation taken at right angles to Fig. 1. Fig. 3 is a plan view. Fig. 4is a vertical section on the line 4 4, Fig. 3. Fig. 5 is a deta'il sideelevation of one of the valve cylinders or members. Fig. 6 is a similarview of the other one of the valve-cylinders. Fig. '2' is a plan sectionon the line 7 7, Fig. 4. Fig. 8 is a detail vertical section on the line8 8, Figs. 1 and 7-, the float-chamber being omitted. Fig. 9 is a planview of the two valve members or cylinders, partially broken away.

cylinders at the opposite extreme of the 1 movement from thatrepresented in Fig. 9. Fig. 11 is a side elevation of the twovalvecylinders, showing the valve in the position of its maximum size ofopening; and Fig. 12 is a similar view showing the same in the posi}tion of its minimum size of opening.

1 is the air-inlet passage, which may communicate directly with theexternal atmosphere or be supplied with air from any suitable source,and diametrically opposite this passage is a connection 2 of anysuitable form and adapted to be attached to the inspiration-pipe of theengine or other .a' aratus in connection with which the cai ureter is tohe used. These two passages 1,2 are formed on a valve-housing 3, and inthis 7v housing, which has a cylindrical interior, are accurately fittedtwo t-elescoped cylinders or cups 4 5, whose upper ends are closedbytops 6 7, respectively, while their lower ends are open and restdirectly upon the bottom of toe 7 5 housing 3, so that the side walls ofthese valve-cylinders 4 5 will project across the passages 1 2, andhence may be utilized as a valve for regulating the amount of airpassing through the passages 1 2. The outer cup or cylinder 4 isprovided in one side with a circular aperture 8, whose edge on one sideis formed with a curved or circular notch 8, and this cup or cylinder 4on the sidediametrically opposite the aperture 8 is formed with asimilar aperture 9 and a similar notch 9"; but,the notch 9" instead ofbeirigdir'ectly opposite or in line with the aperture 8 is'on theopposite side, as indicated by dotted lines in Fig. 5. go The inner cupor cylinder 5 on one side is formed with a oirculai aperture 10 ofsubstantially the same size as the aperture 8 and is adapted toregister. therewith and on the" side of the aperture 10 opposite that onwhich the notch 8 of the aperture 8 is 10- cat-ed is formed with acircular ,notch 10, and on the opposite side of cylinder 5 is formed anaperture 11, which is diametrically opposite the aperture 10 and has inits edge a circular notch 11*, similar to the notch 10, but on theopposite side of the aperture 11, as indicated in dotted lines in Fig.6. Consequently when these two cups or cylinders 4 5 are telescoped andrelatively rotated 05 the apertures 8 9 10 11 may atone time be causedto come into register directly in line with the passages 1 2 andconstitute, through the valve, the maximum size of opening, and thisopening may be decreased in size on both sides simultaneous] by rotatingthe valve members 4 5 n still further degree in sucli a direction astbhcause the notch of the cylinder 5 and thez notoh 8 of the cylinder 4to approach eachother the notches 9 and 11 on the op osite side making asimilar movement. l y thus reducing or increasing the size of thevulve-opening it will be seen that the contraction and expansion arealways made toward and from the center for ex is'ol' the air- )assage,and therefore by situating the gsso ene or other fue'Lsuppl-y 'tntion tothe other one nozzleat-the center of suchair-passoge the fuel will beuniformly'disseminated throughout the entire crossnree of theair-current notwithstanding the'degree of diminution thereof. Such anozzle for supplying the liquid fuel is shownut 12, and in order thatthe current of airmay be better concentrated against the end thereof forsiphoning up the fuel a central itlb assage of consistent capacity isemployer in the icing of a tube 13, arranged lengthwise of the axis ofthe passages 1 2, with its ends rojecting entirely through thevalve-cy'lin era 4 5. One end of this tube, preferably receives theupwardly-projecting nozzle 12, and 'in order that the parts malie-assembled and the tube withdrawn w en desired such end is providedwith a notch or slot 14' for the admission of the nozzle 12. The tubemay be supported in any suitable wiry, as by a standard 15, formedlinorse'mrrerl'fo the housing 3 and having' a s ring-catch 16 for holdingthe tube against on'gysudinzil movemerit. The notches 8"9 10" 11 are ofa size and rom complementary to the exterior of the ends'of the tube 13and are" adopted to fit around the same when the valve-opening isreduced to its minimum, thus confining the air-current to the tubeallo'ne. v

The valve members or cylinders 4 5 are so connected that the rotationof. one in one direction imparts an opposite direction of ro- To thatend the outer ylinde is provided with an operating'hendle or lever 17and between the two heads 6 7' is situated a lever 18, which is pivotedeccentrically to the upper head 6 by screw or pin 19 end has one endpivoted, by

means of" pin 20, to it fixed support '21, se-

cured by screws or other means 22 to valvehousing 3, the pin passingthrough a curved. slot 23 on the head 6, so as to allow the head 6 torotate with relation to pin 20. The oppo'sitc end of lever 18 isconnected by a pinor ivot 24 to the lower head 7, which is for-me ,witha slot 25 for the reception of said pin 24, and which slot permits thelever to oscillate notwithstanding HS ecccentric pivot 19; but the slot25 being formed racylinder?) in the opposite direction, thereby bringingthe side notches in the cylinders to ward and around the tube 13 toreduce the valve-opening or else forcing them apart to increase thevalve-opening.

In order to prevent leakage of air through the slot 23, the support 21may be formed with an overlap ing extension 26. It is of course obvioust at should the tube 13 be removed the valve might be stillfurtherclosed notwithstanding the side note-he's 8" 9, &c., although theopening on one side of the valve would begin to enlarge afterthe-minimum on that side is reached but the converging wells of thecylinders on the opposite side submitting another nozzle of a different08 paoity, the passage of the nozzle 12 being of course in communicationwith the groove; 29, so that the' fuel may ass into the nozzle, and ifthe-nozzle should econie obstructed a wire or straw may bepassed-through it The up or end of the'nozzle is situated substantin lyon a level with the redetermined level: of the fuel and chamber 7, whichcontainsa float 32, controlling a valve 33 for stopping the supply ofgasolene at the roper time. The amount of gaso'lene sufiplie through thenozzle 12 may be oontro ed in two ways, either by substituting adifferent size of nozzle or by varying the levelof the fuel in thefloat-chamber. In some instances the latter valve-seat of the valve 33with'relatio'n to the.

level at which the end of the nozzle is situated, whereby thegaso'lenewill rise to a higher or lower level before the valve closes.This valve-seat is shown at 34'and is formed on a fitting 35, which hasa connection 36 for the supply-pipe, (not shown,) the passage 37 of theconnection 36 being situated above the valve 33,as shownin Fig. 4. Thelower end of the fitting is provided Witlte neck' 38 loosely journaledin a bushing 39 and held against withdrawal bye or screw 40; passingtheir h the bushing 39 and into'a groove 41 in nec 38, and the bushing39 is screwthreaded in a cap 42,wlfic'h closes the top of thefloat-chamber in such a way as to be adloo 21; valve housing. havin sovalve-housing having a passage th erethrough, cylindrical telescopevalve members arjustable with relation to said cap. Hence it IS seenthat when the bushing 39 is rotated in one direction the valve-seat 34will be elevated and in the opposite direction will be 5 lowered and yetthe position of the connection 36 for the supply-p1pe willnot bematerially changed.

Should it'be desired to prime the carbureter, the float 32 may bedepressed by a button 43, which extends through-a stuff ng-box 44 andbears against pin 45, which is ar ranged to impinge the upper end of thevalvestem 46, the pin 45 being elevated by spring 47, arranged in a cap48 on the upper end of I fitting 35.

Having thus described my in vention,'what I claim as new therein, anddesire to secure by Letters Patent, 1s
